The same letters of reference are employed to indicate like parts in all the figures. In the spindle illustrated in Figs. 1 and 2 the carrying part a' formed as a spindleblade a is .shown as furnished with a conical foot b and adjacent taper portion vc to fit a footstep at the 'lower end anda cylindrical part d to form an upper journal andis shown as mounted in a bolster e. The bolster e is shown as adapted to be mounted in a rail being furnished with aflange f to rest upon the rail and with screw-threads to receive a n ut g by which it'ina be secured in position. The bolster e is further shown as having in its interior the footstep h and a cylindrical bearing i in the upper part with an intervening Wider portion or cavity j serving as a holderA for some reserve of lubricant, 7s being a hole through which lubricant Amay be supplied. The bolster e is also shown as having on its exterior at lthe upper part a journal Z to receive and support and to keep always apart from the spindle blade-7?J the driving part m shown as a wharve or pulley n with a sleeve 0 adapted by the provision `of a flange p to receive a washer g of yielding frictional material such as flannel and in the case represented a central collar r is also formed around the central hole of the driving part. m to prevent thewasher g from moving eccentrically and passing into contact with the spindle-blade a. .A flange or collar s to bear upon the washer g is shown as provided to transmit motionl from the driving part m to the spindle-blade a., The frictiontransmitting device shown as. a collar s isl shown as provided with a boss t having at the lower part a flange u of diameter equal to that of the flange p and in the case represented also with acentral cavity /v to receive the upper edge of the collar r and thereby to guard against the washer g being caught be tween the' flange u and the spindle-blade a 'fr the upper end of the bolster e. The collar s is formed internally with a hole 'zo of a diameter allowing it to be moved .freely up or down and coaxiallyY wil-li a cylindrical part l of the spimllebladrl a, so as never to blade-or yarn or thread thereon and so never to be pressed thereby toward the 4driving part m. A groove m to receive a key y secured in the spindle-blade a is formed in the collar in order that the collar s and spindleblade a cannon be turned independently of onel another. The collar .s serves by its weight to press the ange u againstl the washer 'g and the washer g against the flange p. The central boss tot the collar or flange s may serve to receive a few 4coils of yarn or thread after the completion of one cop or bobbin so as to hold the yarn or thread in readiness to be wound at the commencement ofthenext cop or bobbin in the manner usual in ring-spinning machines and a groove a formed in the boss s may enable the .coils of yarn accumulating thereon in use to be -cut away or pulled oil' easily from time to time. The spindle-blade a is shown reduced in diameter and tapering upward above thecylindrical part on which the coli lar or flange s is mounted and is shown in Fig. l as furnished with spring packing in the form of `an elastic sleeve on which a to be wound may be placed so as to beheld firmly in position upon the spindleblade a. Any means desirable for preventing the spindle-blade a and collar or flanges from the bolster e in use'may be used. Y A

-There may be provided if desirable in any case any convenient. means ofpreventing paper tubes and other bodies to receive yarn or thread from being pushed so far down frietion-transmitting-device s, a collar'2 applied to the spindle-blade a against a shoul- .y der 3 thereon being one\such means. In the spindle the driving part mcomprising-'a wharve or pulley is formed so that the washer .g may bear upon' it and the bolster e is shorter than that represented in Figs. l and 2 to an extent corresponding to the shortening of the driving part. wt. The collar s used in the spindle represented in Figs. 8 and il is made to lit upon the carrying part formed as the spindle-blade a so as easily to be moved lengthwise thereof and coax? ially therewith and to surround the upper edge of the ctllar 7 upon the driving part vn, and -is provided in its upper end'wit-h notches ft to receive keys 5 formed on and projecting from a. collar 6 fast upon a spindle-blade a and serving to transmit motion from the collars to the spindle-blade a and if desirable to receivey coils vof yarn at the completion of cops or thel like. The collar 6 is fixed in such a position and the notches fland keys are formed of such relative dimensions that the collar .v can in .use never bear any part of the weight of the spindle- ,bladea or kyarn o'r thread thereon. The

bear any part of the weight of the spindle` collar 6 is formed With'a groove 7 serving A paper or like tube on which yarn or thread is I being accidentally displaced or removed from the spindle-blade a asv to bear upon the ing part the same urpose as the groove e. In other respectsl t e spindle represented in Figs. 3 and 4 issimilar to that represented in Figs. 1and2. 4

4 The spindle r presented in Figs. 5 and 6 is similar in `construction to that represented inFigs. 3 and 4 yexcept in that t-he driving part m, the flange` or collar s-and 'the collar 6 are of larger: diameter, in Athat the collar 6 is provided with a concave upper surface 8 wih a circumferential flat- -surface 9 to support a bobbin, in that the spindle-blade a is cylindrical from its upper bearing to the upperend. ,The spindle represented in Figs.` 5` and disintended for use in wind- .ing yarn or thread upon large flanged bobbins such as are'used to hold yarn or'thread for usein forming warps and in the use ofthe spindle it will ordinarily 'beponf venient, as is customaryinthe winding of yarn or thread on to similar bobbins placed upon spindles, like should be placed on and made to adhere to the surface 9.

In the spindle illust-rated in Figs. 7 and 8 is provided a friction-transmitting-device` s formed as a collayr with a pin lOengaged with a-hole 11 in aftlange 12 formed around a collar 6 fast upon -the spindle-blade a in such a position above the friction-transmitting-device as never to rest thereon, the pin 10 being freel to move up and down in the hole 11 while able to transmit motion to the collar 6 and spindle-blade a.

In each of the spindles represented in the accompanying drawings, the driving part m is clearly s hown as being carried by the bolster e so as never to be able to pass into contact with the spindle-blade a and the friction-transmitt-ing-device s which receives motionthrough the wlasher q from the drivm being free to move lengthwise of the'spindle-blade a is free to be raised to any extent requisite from the driving part m by the washer g according as a thicker or thinner washer q may be in use trom time to time without ai'ecting the proper bearing of the lower end of the spindle blade a, in the footstep'hor allowing the weight of the spindle-blade or yarn thereon to modify the friction available for the transmission of motion. Consequently the friction between the driving part. m and the washer g and between thev washer q and the collar s forms the only means for transmitting motion from the driving part 'in t'o then spindle-blade L and the weight and 'friction of the collar s against the washer q are not..a`tl'ect'cd by the weight. oi yarn or thread Wound upon a tube or bobbin or other body applied to the spindle-bladeI a. At all stages therefore of the winding` the yarn orthread being wound may without being thereby strained orwbroken hold back the spindle-blade a against revolving with the vis allowed to pass that a washer of fel-tor the,

driving part m'either so a's onlfyto allow the spindle-blade a to revolve at a speed .corresponding to that at which yarn onthread yarn or thread requiring to b pieced' after breakage or the termination' of the yarn or thread to hold the spindle-blade a against revolution or -to allow it to be upon 1t.

toit or in the case of a turned backward by the yarn' or thread be-' l `ing pulled 0H the body of yarn or thread 75 The bolster e may be formed so asin any- Icase to extend for any desirable distance into the friction-transmitting-device. In each ot' l the cases represented the bolster e extends approximatelyto the upper edge of the collar 1 and to that extentinto the frictiontransmitting device s, but in cases in which the collar o and `cavity e are provided and also in cases Ainv which they are dispensed with the bolster ef may extend for any desired distance toward, into or throughout the friction-transmitting-device and if extending therein m'ay whenever this may be desirable also serve as a journal therefor.

By this 'invention it will be seen 'that variation in the thickness of frictional driving pads and variation in the weight applied to the carrying parts of spindles by the yarn or thread and any other bodies carried thereon are prevented from .causing variation in the pressure applied-to bring about the transmission of motion from the driving parts to the carrying part-s and also insures that the carrying parts of the spindles shall always be able` to bear properly in their footsteps and any other bearings used and thusenables jus/t the friction suitable in each case tobe provided a d enables the carrying parts of the spindls to be driven easily and also whenrequisite also to be held back revolution and if need be to be turned back by yarn or'thread being pulled oit without risk of'yarns or threads even of the mostv delicate character intended to be wound in any particular case being strained or broken.

Obviously the details of spindles constructed according to this invention `may be varied in different cases as may be requisite without departure from the principles of this, invention as set forth herein and in the claims following.
